To determine how much Amal will spend on school supplies, we need to add the prices of all the items he intends to buy:
- Notebook: $2.75
- Binder: $3.49
- Pack of pencils: $3.55
- Pack of pens: $5.75
Now, let's add these amounts together:
\[ 2.75 + 3.49 + 3.55 + 5.75 \]
Calculating step by step:
- \(2.75 + 3.49 = 6.24\)
- \(6.24 + 3.55 = 9.79\)
- \(9.79 + 5.75 = 15.54\)
Thus, Amal will spend a total of $15.54 on school supplies.
